Abstract

We study the implication of the recent \ensuremathΔM_s measurement on b\ensuremath→sqq transitions. We show that it is possible, in the presence of a flavor symmetry, that the phase in B_s mixing may be unobservable even with new CP odd phases in b\ensuremath→s transitions. These phases may then produce new CP odd effects in certain b\ensuremath→sqq transitions like B\ensuremath→K\ensuremathπ but not in others like B_d\ensuremath→\ensuremathφK_s. Working in a two Higgs doublet model of new physics we discuss the allowed NP contribution to B\ensuremath→K\ensuremathπ and B_d\ensuremath→\ensuremathφK_s decays with the new \ensuremathΔM_s measurement.
